Filed: 2000-01-18
Granted: 2003-05-20
Abstract: In one embodiment, a cordless telephone according to the invention includes a base unit, including a paging mechanism, and a handset, including an alerting mechanism responsive to the paging mechanism. At least one of the base unit and the handset includes a page adjusting mechanism to affect an alerting signal output from the alerting mechanism based on a condition. Thus, the paging signal is adaptive to increase the opportunity for a user to determine the location of a misplaced handset. In another embodiment, a cordless telephone is equipped so that the base unit can provide an indication related to a distance between the base unit and the handset. In yet another embodiment, a cordless telephone is equipped so that the paging mechanism is adjusted based on user control. In a further embodiment according to the invention, a method is provided for affecting an alerting signal output by an alerting mechanism of a cordless telephone handset. The method includes the steps of sensing a condition, and affecting the alerting signal based on the sensed condition.

Abstract: Disclosed is a spread spectrum multiple access coding technique relevant to wireless digital telecommunication systems involving Code Division Multiple Access and spread spectrum techniques. The group of basic pulses has normalized amplitudes and duration of 1 and polarity; the number of basic pulses is ascertained by practical factors; there is no equal interval between basic pulses on time axis, and asymmetry of pulses' positions is employed to achieve arranging coding. This coding scheme can control and minimize the side lobes of auto-correlation and cross-correlation functions, then simplify the design of a CDMA system, so a wireless digital telecommunication system with large capacity can be established effectively to solve the contradiction between ever increasing demand for telecommunication capacity and limited frequency resources.

Abstract: A method of detecting a first cow when mounted by a second cow is described. One or more beams of light are directed wholly or substantially horizontally at one or more detectors, and at a level above the first cow and corresponding to the additional height of the second cow when mounting the first cow, such that the mounting of the first cow by the second cow breaks one or more of the beams of light to one or more of the detectors, and the or each detected break causes activation of an alarm means or a cow identification means or both. Mounting is an indication to the farmer that the cow is ready for insemination, and the invention provides an automatic method of alerting when a cow on heat, or immediately identifying a cow on heat, which is only activated as and when the cow allows herself to be mounted. Preferably, two or more beams of light and two or more detectors ar e used, and the detectors work in partnership to coordinate two or more differently located cameras to the location of breakage of the light beams.

Title: Partial back pressure (pbp) transmission technique for atm-pon
Inventor: KIM KYEONG-SOO
IPC: H04L12/56
Filed: 2001-03-28
Granted: 2006-05-30
Abstract: Efficient transmission and fairness guarantees for upstream traffic in ATM-PONs are achieved using a partial back pressure (PBP) technique for traffic generated from user network interface (UNI) cards, e.g. Ethernet UNI cards or other network interface cards for non-constant bit rate sources. The PBP technique utilizes a feedback flow control mechanism between priority queues and UNI cards in a customer-side interface device, e.g. an Optical Network Termination unit, to achieve improved transmission efficiency and fairness guarantees of incoming traffic. The peak upstream rate of the UNI cards is dynamically controlled based on feedback information from the interface device where a queue status monitor observes the traffic level in the priority queue. Upon reaching a designated threshold level in the priority queue, the status monitor triggers activation of rate controllers in the upstream output of the UNI cards. The rate controllers reduce the peak output of the UNI cards to a controlled peak rate.  Once the queue level is reduced beyond a second threshold level, the status monitor deactivates the rate controllers.

Title: Handoff in radio telecommunications networks
Inventor: MADOUR LILA
IPC: H04W36/10
Filed: 2001-08-16
Granted: 2006-07-25
Abstract: The invention relates to an improved handoff method for mobile IP in a cdma2000 network. During handoff, the A10 connection between the Target PCF and the PDSN is pre-set-up, while the MS is still connected to a MSC, when the Target PCF receives the message from the Target BSC to set up the A8 connection. Furthermore, in the case of inter-PDSN handoff, a tunnel is established between the PDSNs, over which the PPP context eventually is transferred to the Target PDSN. The Target PDSN then sends a message to the MS triggering a re-registration with the HA. The Target PDSN takes over full responsibility for the MS when it receives the Mobile IP Result from the HA, and sends a message to the Serving PDSN to let the latter know that it can release all resources related to the MS.
